I think this prob. is more difficult---->

I go to a beach and scoop-up a glass of (sea)water.
I put it back in, and the ocean is shuffled, completely homogenized.
I again scoop-up a glass of (sea)water.
How many (sea)water molecules (from the previous scoop)
are in this glass?


I'd need to know 2 constants.

54. How many fish are in the pond?

An ichthyologist wanted to estimate the number of fish in a pond which are suitable to be caught. He threw into the pond a net with regulation size
mesh, and after having taken the net out he found 30 fish in the net; he
marked each of them with a suitable colour, and threw them all back into
the pond. The next day he threw the same net and captured 40 fish, of
which 2 had been marked. In what way did he compute (approximately) the
number of fish in the pond? -- David Entwistle

I calculated something similar. Seems surprising.

I was wondering how long that ocean mixing might take. That led me to
another surprising thing: "The average velocity of water molecules in
liquid water at 20 degrees Celsius is approximately 0.6 kilometers per
second (600 meters per second)". It seems surprising they just sit in the glass - I guess some don't...

Yes, that's why water evaporates, and why it gets cooler as that
happens. The faster-moving molecules near the surface escape,
reducing the average kinetic energy - temperature - of the remaining
liquid.
